PHILIP IE. CARROLL, OF JULIET, ILLINOIS.

LONG-LOAF-MQLDING MACHINE.

Specification of Letters Patent.

Fatented Sept. 3,1912.

Application filed December 1, 1910. Serial No. 595,040.

To all whom it may concern:

Be it known that I, Pnniir F. CARROLL, a citizen of the United States,residing at Jcliet, in the county of .Vill and State of Illinois, haveinvented certain new and useful Improvements in Long-Loaf-liloldingMachines; of which the following is a specification.

My invention relates to the art of bread making and refers particularlyto machines employed for shaping or molding the dough after having beendivided into portions of uniform siZe and weight.

The chief objects of the improvements which constitute the subjectmatter of this application for patent,- are to provide means in a doughmolding machine for adjusting the mechanism so as to accommodate the.

panying drawings, which form a part of this application, the details ofconstruction being disclosed in the following views Figure 1 is alongitudinal sectional view of the complete machine; Fig. 2 is an endelevation, and Fig. 3-is a sectional view on the line 3-3 of Fig. 1.

T iferring to the details of the drawings, the numeral 5 indicates sidemembers, connected by cross-pieces 6 to form a. rectangular frame. Journaled in these side members near the rear end of the machine is amain or drive shaft 7 upon one projecting end of which are mounted fastand loose pulleys 8. This shaft 7 carries a drum or roller 9 engaged byan endless canvas apron or belt 10, which extends to the front of themachine where it passes around an idle roller 11 mounted on a shaft 12.T lie lower course of the apron 10 is backed by a board 13 supported ontransverse-rods 14 secured in the frame sides. Above said apron isarranged a feed hopper 15, and immediately beneath this hopper are apair of feed rollers l6, l7, slightly spaced apart to allow the passageof the dough portions one of which is shown at a, at the same tin".exerting a sulticient pressure to convert it into a flattened sheet, asindicated at 0. The rolls 16, 17, are given the proper mot-ion towardeach other, indicated by the arrows, by means of a chain gear 18, whichengages suitable sprockets mounted upon the respective siiafts. In orderto rotate the feed rollers in opposite directions,by a single chain, thelatter passes over the sprocket of one roller and under the other, anexpedient frequently made use of in sprocket gearing, and therefore notshown. The feed roller 16 is furnished with a scraper 19 which iscapable of adjustment by means of a lever 20. The purpose of thisscraper is to prevent the dough from adhering to the roller surface and.also aid in directing the dough mass rearwardly so that it will passbetween the roller 17 and the upper course of said apron 10, theinterval between these members being so regulated as to still furtherflatten the dough. The roller 17 is also furnished with a scraper 21,which is adjustable by a thumb screw 22. Running in close proximity tothe endless band 10 to the rear of the feed rollers is an endless apron23 the courses of which are nearly vertical. This apron at its upper endpassesaround a roller 24, having its shaft- 25, journaled at each end ina block 26, slidably mounted in guides 27 and adjustable by a hand screw28. One end of said shaft 525 is provided with a sprocket- 29, connectedby a chain 30 with a sprocket 31 on the drive shaft 7. The lower end ofthe said apron 23 is supported by a roller which is journaled at theends in hanger bars 3t (Fig. 2) having their upper ends pivoted on theshaft- 25, this arrangcirerrt permitting the rolier 32 and apron toswing away from the apron 10, to permit the passage of the doughportions when properly formed in the manner hereinafter described.

Extending transversely'above the apron 10 is a flour dredge supportedfrom the frame by suitable brackets. Running parallel with and belowthelower course of the apron 10 is a guide plate 31"), the interval betweenthe said apron and plate forming a channel 36 for the passage of theloaves of dough. The upper end of this guiile '1 nel 36. The forwardend. of the guide plate 35 terminates directly beneath the roller 1'2,and the interval between said plate and the end of the frame forms apassageway "which is controlled by a valve 38 pivoted on a. transverserod 39, and adapted to be moved. by a handle 39, secured to said rod tothe position shown in dotted lines in Fig.1, where it rests against astop 4.0, T he said plate 35 is supported at the forward end on a pairof roclearms 41 mountedon a rockshatt 42 extending between the sidetrame. members 5, a lever ,43 attachedto said. shaft 42 permitting ofready adjustment of this end of the said plate so as to vary the depthof the channel 36. The rear end of the sa vl plate 35 is suported upon atransverse rod 35 attached by arms 35* to a rock-shaft so that this endof the plate is adjustable by turning the said shaft, which done byhand. At a suitable distance below the apron 10 is another endless apron44s or tending nearly horizontally, and supported at the front and rearends by rollers 4-5. This belt or apron 4.4 is driven from the mainshaft 7 by a chain 16, and the lower course of the apron is backed up bya board 47, in.. the same manner as the apron i0 is supported fromupward pressure by the board 13, previously described.

Extending parallel with the lower course of the apron 44 isa plate 48,having its rear end bent upwardly concentric with the correspondingroller 45, its forward end also having an upward curve toward the rollerafter which it bent downward at an angle and terminates in a. ledge orflange 49 forming a receiving trough into which the completed doughloaves fall, and from which they are transferred to the baking pans byhand. The said plate 48 is supported upon an adjustable table 50 whichrests upon cross rods 51, fixed in the horizontal arms 52, of bell-cranklevers lse ed on rockshafts 53,the vertical arms 54- ot said leversbeing connected by a link bar 55, so that the said shafts andconsequently the arms 52, will movetogether when operated by a lever 56,attached to the forward rockshaft 53. Provision is made for adjustint:the aprons 10 and it by iournaliug their l'orward shafts in blocks whichslide in guide ways 57 in the frame and are secured by adjusting screwsBetween the apron: 10 and 44- 1s arranged a lifting plate 59, having itsforward end. pivotally supported upon the rock shaft e2, while its rearend rests normally upon the endless band 414 directly over the rearroller 45, so that this end of the plate will be lifted by the doughportions as they are carried rearwardly by 1 sale oer,
